Renewed May 19, 1932.

'(lhe present invention relates to improvements in bubbler caps Vfor oildistilling apparatus, or any hydrocarbon compound, and has for an objectto provide a twin cap which fg will perform a double duty and aid in theAmore eilicient distilling ot the oils, or any hydrocarbon compound.

Another object of the invention is to provide a twin cap device in whichthe usual 3a form of cap may extend in the upper chamber above the tube,while the improved cap will lie in the chamber below and be held inconjunction with the lower end of such tube, whereby caps will beprovided for both ends ne of the tube and in both chambers..

With the foregoing and other 'objects in view, the invention will bemore fully described hereinatter, and will be more particularly pointedout in the claims appended 8O hereto. c V

1n the drawings, wherein like symbols reer to like or -correspondingparts throughout the several views,

Figure 1 is a side elevation of a tower with parts broken away showingthe improved device,

Figure 2 is a cross section taken on the line 2-2 in Figure 1, and iFigure 3 is an enlarged vertical section taken through one of theimproved devices.

Referring more particularly to the drawings, designates the towercontaining the trays or partitions 11, which separate the tower intochambers 12.

The tube is indicated at 13, and is usually four inches in diameter andapproximately nine inches long. Thisftube'13 has-its open upper end disosed in the chamber 12 above, and its open oWer end of the chamberbeneath suchv tray 11. r

1n the form of device heretofore used, an upper cap 14 was provided,being held spaced above the upper open end of the tube 13 as by theshoulders or brackets 15.` This old form of cap 14 is provided with adepending ange 16 of greater diameter than the tube 13 and which extendsdown and overlaps the upper part of the tube, the lower free edge of theflange 16 being serrated pr scalloped,

as indicated at 17.

ln accordance with the present invention, l provide a lower cap 18inverted with respect to the upper cap 14, and ll press this lower-cap18 directly against the lower end of the tube 13 in the chamber 12 belowthe tray 11. The cap 18 is provided with an upstanding circular ange 19,which is of con- Ksiderably greater diameter than the diameter of thetube 13, and forms an annular channel about the-.lower end of the tube13 and Within the flange 19. The lange 19 opens upwardly into theinterior space of the lower chamber 12. The upper free edge of the ange19 is preferably smooth or unprovided with serrations. The serrationsare provided upon the lower end of the tube 13, as shown at 20, theseserrations providing a means of communication between theinterior of thetube 13, and the annular channel conned' within the ange 19,and exteriorof the lower (3@ p part or the tube 13.

. '.lhe lowercap `18 is held in placelbythe bolt 21 having the head 22,which lies above the cap 14, and provided with thenut 23 below thelower cap 18,"the bolt passing through both caps 14 and 18. Of course,the head 22 might be disposed down below (za-p18 and/ the nut 23 abovecap 14, if desired. The bolt holds both caps in place in a tightA andsecure manner. @o

ln operation, the vapors carrying mpre or less of the entrained liquidfrom the tray in the lower 'chamberascending strike the tray 11 andenter the mouth of the annular chamber within the flange 19 ofthe lowercap 13. As the vapors enter the annular chamberL formed by cap 1'8, theentrained liquid is deposited in said chamber.

From such annular chamber, the vapors pass through the slots orserrations 20 and enter the lower part of the tube 13, ascending in suchtube until the same strike the up per cap 14. This upper cap tends tokseparate or deflectthe vapors and to guide them downwardly through theannular chamber within the flange 16, and the vapors pass out'downwardly through the serrated edge 17 and'into theupperfra'ctionating chamber.

In this way, a double duty isperformed by the improved tubes 13 whichcarry twincaps,l 163 lnely, one cap above and 'a companion cap Fi res 1and 3 illustrate how the liquid stan in the trays in and around thecaps. In Figure 1 is shown a leg 24 or channel for the liquid to flowback or reflux, as indicated by the arrows. The vapors travel upwardlyas also indicated by the arrows.

According ,to my method a double distillation takes place because theoil and vapors pass through a double set'o caps. Also as the condensedliquid overflows from the lower caps, it is sprayed into the lowerchamber and exposes more surface for evaporation. There is a doubleliquid seal of the vapors. This method is especially good for vacuumdistillation, where the vapors are drawn and not forced through. Thisdouble distillation will produce better fractionation with less trays.

It be obvious that many changes in the construction, combination andarran ment of arts could be made, which could used'wit out de artingfrom the spirit of my invention, and do not mean. to limit the inventionto such details, except as particularly ointed out in the claims.

` ving thu'sdescribed my invention, what I claim and desire to secure byLetters Patent of the United States is t- 1. An im roved bubbler capdevice comprisin a. tu a-nupper anged cap held in space relation abovethe upper end Aof the tube, a secondcap invertedwith respect to theupper cap and ed against the lower serrated portion o the tube, anupstanding flan on the last mentioned cap, and means palng through bothofA said caps for suspending the lower cap from the u per cap.

' 2. An im roved bubbler cap evicecomprisin a tu an upper flange capheld in space relation above the upper end of the tube, a second capinverted with respect to the upper cap and pressed against the lowerserratedportion o the tube, and an upstanding flange on the lastmentioned cap.
